Definitions

  • the invention relates to a transport container made of plastic for liquids, in particular high-purity liquids, with an immersion tube extending from a container top wall to the container bottom.
  • transport containers are used to transport liquids.
  • an immersion tube is required for emptying, which extends approximately to the bottom of the container and is provided with a screw connection at its upper end.
  • the immersion tube usually consists of a different plastic material than the container of the transport container produced by blow molding. Such immersion tubes are sealed in the top wall of the container. The work and costs involved are considerable; additional measures for quality assurance are also required.
  • the object of the invention is therefore to design a transport container of the type mentioned at the outset in such a way that it can be produced with relatively little effort and, in particular, that no measures are required for retrofitting an immersion tube.
  • the dip tube is thus already produced during the manufacture of the plastic container of the transport container, so that no further manufacturing and assembly work is required.
  • the production of the plastic container is not significantly more expensive for the same production batch size, but the effort for the separate attachment of a dip tube is eliminated.
  • the A- piece design of the immersion tube enables the attachment of a level sensor in a simple manner.
  • the reduction in the number of structural components of the transport container due to the one-piece design of the immersion tube likewise reduces the production outlay and at the same time also reduces the possibility of errors during assembly and handling. The cleaning effort is also reduced.
  • the immersion tube is preferably formed in an inner projection, running along a surface line, of the essentially cylindrical container wall of the transport container. Due to the solid, one-piece connection of the dip tube to the container wall, the dip tube is fixed over its entire length to the container wall, so that bending stresses that could occur due to liquid movements with a dip tube protruding freely into the transport container are completely avoided. In particular, it is also not necessary to provide a separate fastening at the lower end of the immersion tube which projects into the immersion container, as may be necessary in known transport containers with immersion tubes which project freely into the interior of the container, at least with a longer immersion tube length.
  • the transport container is preferably a hollow body produced by blow molding.
  • the transport container For use with high-purity chemicals, it is expedient to produce the transport container as a hollow body by coextrusion blow molding, the inner wall material which is particularly selected with regard to the chemicals to be taken in lining both the inner wall of the container and the dip tube, so that all surfaces in contact with the product are made from this inner wall material be formed.
  • 1 is a transport container for liquids in a longitudinal section
  • FIG. 2 shows a plan view of the transport container according to FIG. 1,
  • FIG. 4 shows a side view of the transport container according to FIG. 1 in the direction of arrow IV
  • Fig. 5 shows a modified embodiment of a transport container in a longitudinal section corresponding to FIGS. 1 and
  • the transport container shown in FIGS. 1-4 consisting entirely of plastic, is used for receiving, storing and transporting high-purity liquids. It is made by blow molding and is made of polyethylene (PE), for example.
  • PE polyethylene
  • An integrally molded dip tube 1 extends from a container top wall 2 to a point lying a short distance above a container bottom 3. As can be seen in particular from FIG. 3, the immersion tube 1 is formed in an inner projection 4, which extends along a surface line of the essentially cylindrical container wall 5. Stiffening ribs 4a hold the dip tube 1.
  • the dip tube 1 is provided with a screw connection 6 on its tube end opening into the container top wall 2. For this purpose, an internal thread is formed at the upper end of the tube, into which a removal screw connection can be screwed.
  • the dip tube 1 serves as a removal tube for emptying the transport container.
  • At least one closure opening 7 is provided in the container top wall 2, which can also have an internal thread for receiving a screw closure.
  • Fig. 2 is indicated by a dash-dotted line that a ne further closure opening 8 in the same design as the closure opening 7 can be provided in the container top wall 2.
  • the immersion tube 1 is widened at its mouth located in the region of the container top wall 2 in order to create sufficient space for the screw connection 6.
  • the connection screw connection can be provided with a filling-related mechanical encryption, which prevents confusion with a container of the same type, which contains another product, during the manufacture of the removal device.
  • an inner container 8 provided with the integrally molded dip tube 1 made of plastic, which in essentially corresponds to the embodiment according to FIGS. 1 and 4, is inserted into an outer container 9 made of steel.
  • the outer container 9 is preferably made of stainless steel and essentially serves to mechanically reinforce the transport container.
  • Its cover 10 has an access opening 11 and 12, respectively, in the region of the mouth of the immersion tube 1 and the closure 7 (and possibly the further closure 8).
  • the one-piece transport container shown in FIGS. 1-4 or the inner container 8 in the embodiment according to FIGS. 5 and 6 can be made by coextrusion.
  • Blow molding can be produced, an inner wall material specially selected with regard to the liquid to be absorbed lining both the inner wall of the container and the dip tube 1.
  • the transport container can be designed in different sizes and shapes.
  • the illustrated embodiments can be implemented with a height of approximately 900 mm and a diameter of approximately 600 mm, so that they have a gross volume of approximately 200 l.
